and this when trying to use the 'php setup/setup.php install config.json' command
$Could not find composers "autoload.php". Try to run "composer install" in the directory ".libs/composer"$

I'm in a bit of a hurry to get ILIAS up and running, so your help would be much appreciated!

Thank you in advance,

Hello, 

I accidentally typed the code incorrectly - it's the first time I am doing this so my apologies!

I have now attached this in *.txt format. When replying, please remember to scroll a lot to the right, as the code pasted earlier did not wrap and is one huge line. Then you will be able to see the reply screen.

Thank you once again, 
Jakub

Hi jroj,

see:  https://docu.ilias.de/goto.php?target=wiki_1357_Required_and_Supported_Software_ILIAS_7
or:  https://github.com/ILIAS-eLearning/ILIAS/blob/release_7/docs/configuration/install.md#system-requirements
or:  line 11-12 in your 'composer-error.txt'

to see, that ILIAS 7.2 does not run with PHP 8.0, but with PHP 7.3-7.4!

This is the very next requirement you have to fix...

Hello Uwe, 

Thank you so much for your help. 
Unfortunately, now I am facing yet another problem.

I have downgraded from php 8.0 back to 7.4, and when I go to run the 'php setup/setup.php install config.json' command, I now face this:

root@instance-20210919-1440:/var/www/html# php setup/setup.php config.json
PHP Warning: require_once(/var/www/html/setup/../include/inc.ilias_version.php): failed to open stream: No such file or directory in /var/www/html/setup/cli.php on line 10
PHP Fatal error: require_once(): Failed opening required '/var/www/html/setup/../include/inc.ilias_version.php' (include_path='.:/usr/share/php') in /var/www/html/setup/cli.php on line 10

What should I do now? Your help would once again be much appreciated. 

Many thanks, 
Jakub Roj

Hello Jakub,

it looks to me like an 'incomplete' ILIAS codebase folder.
The PHP-Warning states: ... no such file or directory in /var/www/html/setup/cli.php ... ,
so I assume your local codebase folder - where you checked out or unpacked ILIAS - is:
  /var/www/html/
, right?

If the codebase would be complete, then there must exist:
  /var/www/html/include/inc.ilias_version.php
or, in an equivalent path coding:
  /var/www/html/setup/../include/inc.ilias_version.php
(as written in Warning and Fatal Error).

Check this!

Best regards.

Thank you, Uwe, for your help. 

I'm sorry it took me so long to reply. Your support and solution helped me very much and everything is working now! 

Thank you once again, 
Jakub

You're welcome.
